We seek to understand how populations respond to natural and anthropogenic perturbations such as habitat destruction and degradation, disease outbreaks, and novel sources of mortality (e.g. wind turbines). We use a variety of quantitative approaches, including mark-recapture modeling techniques to estimate vital rates of bat species. Â Demography and population dynamics of bats are relatively poorly understood due to the logistical challenges of studying nocturnal, volant, cryptic and often wide-ranging animals.
